Country Code +1:
- +1 is the international dialing code for countries that are part of the North American Numbering Plan (NANP).
- The NANP includes countries such as:
- The United States (including its territories like Puerto Rico, Guam, and the U.S. Virgin Islands).
- Canada.
- Bermuda.
- Several countries in the Caribbean, including the Bahamas, Barbados, Jamaica, and more.
- In these countries, the phone numbers usually follow a structure like this: +1 (area code) xxx-xxxx.
Area Code 647:
- Area Code 647 is an overlay area code in the Greater Toronto Area (GTA) in Ontario, Canada.
- Toronto, Canada’s largest city, and surrounding areas, including parts of York Region and Peel Region, are served by this area code.
- Overlay area code means that this area code was introduced to serve the same geographic region as an existing area code—in this case, it overlays with the 416 area code (the original area code for Toronto).
- 416 is the primary area code for Toronto, and as demand for phone numbers increased, the 647 area code was introduced in 2001 to ensure there were enough available phone numbers.
- Other area codes in the GTA include 437, which is another overlay area code for the region, as well as 905 and 289, which serve surrounding regions in Ontario.
Key Points about Area Code 647:
- Location: Covers parts of the city of Toronto and several suburban regions around the city.
- Population: This area code serves a densely populated and diverse urban area.
- Phone Number Format: Numbers typically follow the format: +1 (647) xxx-xxxx.
The introduction of overlay area codes like 647 helps accommodate the growing demand for new phone numbers without changing the structure of the existing phone system or requiring people to change their numbers.
